Hi, i've build robot grizzly and participated in a robotic contest at my college. I ended up 2nd. Currently i am building a robotic hovercraft with 5 sonars that maps the environment. It uses 2 optical mice and an electronic compass for route-retrieving, it recharges it's own battery when it's on low power. The robot carries a colour video camera and has a graphical user interface (GUI) with all the data that it collects. Want to know more or want to help me? I am founder and member of the belgian robotics club, and most of my members are European. My interests are mainly hardware, but currently i am learning to program in assembler. For the moment, i try to reach my goals in Basic- syntax.
